MONTGOMERY — Alabama prison officials told a federal judge they are increasing staffing as part of a court case over mental health treatment but said they can’t do anything permanent without more money.

The state has increased recruiting efforts and is enlarging the size of its training classes for correctional officers, according to a document filed by the Department of Corrections in federal court Monday. The agency said it began a process more than two months ago to almost double mental health staffing in prisons.

But making improvements in the system will require about $10 million annually that Corrections doesn’t have, the agency said, and it says it’s up to the governor and the Legislature to provide the money.
